From what I know raspberri pi is a small device used to program things like cameras, often used on 3d cameras. But I didn't think you could run a computer with it. I usually build my own. I look at forums to see what the latest best thing is, and check the price, hair stands on end, goes back to see what the second best thing is. And go with that. Once you have the base parts, provided they didn't change the power system like they did with me, a lot of it can be used again. Video card, power, case, drives, etc. The only things I replace are the motherboard, ram and chipset. Probably a new cooler as my current one I think is breaking down. Depending how fancy you are, it won't cost a ton. Maybe now it will but at some point it might go down.
At some point i'll use rasperry pi to control my printer and get a different web cam for it. But that's a learning curve on its own.
